In jQuery, does creating an element with CSS method without a unit give the element a default value?

Suppose I have the following line of Code to create an anchor link:

$('<a>').css("width", 100)

The <a> has width of 100. However, I did not give 100 a unit. Once the element is created and added to DOM, will it be given a width of 100px?

>Solution :

According to the documentation:

When a number is passed as the value, jQuery will convert it to a string and add px to the end of that string. If the property requires units other than px, convert the value to a string and add the appropriate units before calling the method.

The answer to your question is yes, it will be given a width of 100px.
